1。Fedora-12-x86_64-CDS与Fedora-12-x86_64-Live什么区别？
2。Fedora-12-x86_64-CDS与Fedora-12-source-CDs什么区别？
我了解32 和 64位的含义。但是不明白surce什么意思？这些都是什么版本啊？
还有Fedora-12-ppc-CDs,Fedora-12-i686-live.这里686和x86_64什么区别？
ppc什么意思呢？
谢谢。
3.我在Fedora12上，运行yum upgrade

请问这是怎么回事呢？我运行升级，他怎么会“Running rpm_check_debug”，出现“Transaction Check Error:”
我自己建立了/boot filesystem这个目录。
以后出现这些东西我都不理解，怎么会出错。请高人解释。谢谢您的关注与付出的劳动。
